A solution of quinolin-3-yl-methanol (227, 3.1 g, 19.5 mmol) and thionyl chloride (Aldrich, 16.5 mL, 195 mmol) in 50 mL of benzene was refluxed for 3 h. After cooled to room temperature, the solvent was removed under reduced pressure to dryness. This crude product was used directly in the next reaction. 1H NMR (400 MHz, DMSO-d6) δ 9.20 (s, 1H), 8.82 (s, 1H), 8.21 (d, J=7.9 Hz, 1H), 8.19 (d, J=8.1 Hz, 1H), 7.97 (t, J=7.4 Hz, 1H), 7.81 (t, J=7.5 Hz, 1H), 5.09 (s, 2H). MS (EI): m/z 178 (M+H). Quinolin-3-yl-acetonitrile was synthesized from the above crude product, KCN, NaHCO3 and KI in similar manner as described in Example 221. 1H NMR (400 MHz, DMSO-d6) δ 8.87 (d, J=2.0 Hz, 1H), 8.36 (s, 1H), 8.05 (d, J=8.3 Hz, 1H), 8.03 (d, J=7.8 Hz, 1H), 7.79 (t, J=7.3 Hz, 1H), 7.65 (t, J=7.8 Hz, 1H), 4.31 (s, 2H). MS (EI): m/z 169 (M+H).
